Inventor: NAGASE SHIRO
IPC: B41N10/00
Filed: 1989-02-06
Abstract: PURPOSE:To obtain a sqeegee blade with an edge section which does not peel off by injecting resin material into a cavity for forming a blade to form a holder, then injecting a different type of resin material to form an edge section and allowing a resin material to cross-link the formed edge section. CONSTITUTION:Resin material is injected into the cavity for forming a blade of a die to form an edge section 5. Next the resin material in the edge section 5 is solidified in a non-cross-linked state, then a different type of resin material (which is of the same composition as and harder than the edge section 5) is injected to form a holder section 4 so that it runs along one side of the edge section 5. In this case, the material resins of the edge section 5 and the holder section 4 mutually melt together at the border. The material resin of the holder section 4 becomes hardened as not yet cross-linked, then the die is placed in a heating furnace to cause the material resin to be cross-linked. After this, the molding is released to take out from the die as a blade.

Title: Washer solution feeding device
Inventor: UDA KAZUHIRO
IPC: B60S1/48
Filed: 1985-02-15
Abstract: PURPOSE:To prevent the occurrence of a lag time with which a washer solution is injected from a nozzle after a pump is driven, by a method wherein a device is constituted such that the washer solution can be held in a pipe through which the pump is coupled with the nozzle. CONSTITUTION:A leak flow passage 30 formed with a 3-way joint 18, a drain pipe 19, and a leak valve 20, is located to a lower part in the vicinity of a front nozzle 17. When a washer solution is fed, a flow passage switching valve 13 is energized to drive a pump 12. This causes the washer solution to be fed to the front nozzle through a front pipe 16. In which case, the washer solution flows to the leak valve 20 through the 3-way joint 18 and a drain pipe 19, but since a pressure produced by the action of a pump is exerted on the washer solution, a ball 22 is pressed against a sheet 23 to prevent leak of the washer solution. When injection is stopped, a valve 13 in the front pipe is closed, and this causes the washer solution to be held in the front pipe 16.

IPC: G03G15/20
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To keep the temperature rise at a non-paper passing part constant even when continuously fixing narrow recording paper by providing plural heating parts with a positive resistance temperature coefficient connected in parallel between two electrodes, which are partly different in heating per unit length in the longitudinal direction of a cylindrical base. SOLUTION: A heating unit 14 is formed by connecting in parallel heating parts 14a and 14b, and the heating part 14a is rectangular wave-like meandering in a region Ps and extended rectilinearly in a region Pn. On the other hand, the heating part 14b has a reverse constitution to that of the heating part 14a. Accordingly, the heating values of the heating parts 14a, 14b are such that the heating part 14a if larger in the region Ps and the heating part 14b is larger in the region Pn. When small-sized paper is continuously passed, the passing area Ps temperature is instantly lowered, but such lowering is detected by the thermistor to apply an electric current to the heating unit 14 by a control circuit, thereby returning the temperature to a preset temperature.  Though the temperature rises in the region Pn, the heating unit 14 is a sef-temperature control PTC heater, and both heating parts are connected in parallel, whereby in the region Pn, the current is restrained when it reaches a preset temperature to restrain heat generation.

Abstract: PURPOSE:To eliminate requirement for enlargement of culvert or increase of capacity of a centralized treating facility even for a large amt. of rainfall by communicating a hole extending toward vertical direction with a culvert and providing a filter having a multilayered structure to the side of the hole. CONSTITUTION:When a large amt. of rain water exceeding the capacity of a centralized treating facility flows in a culvert, the rain water reaches a pipe body through a branch pipe, and the rain water contg. earth and sand passes through filtration plates successively and reaches the bottom of the pipe body. During this stage, a nonwoven cloth 26 constituting the filter member 14 removes the earth and sand by the filtration effect to purify the rain water. The position of the nonwoven cloth 26 arranged in the space 28 is deviated each by 90 deg. from the position of the position of a nonwoven cloth 26 of the each adjacent filter member 14 in the space 28, successively. Therefore, a spiral passage of stream is formed in the space 28, and the rain water in the filtration apparatus flows downward through the filter member 14 forming partly eddy steam and reaches the bottom of the pipe body.
